Spring MVC stop refreshing the page after GetMapping

I am working on a page where I have to retrieve the "tasks" of a specific date from the database. My current approach is to use GetMapping at the server, and return the list of tasks

Below is part of my TaskController

@Controller
@RequestMapping()
public class TaskController {

    @Autowired
    private TaskService taskService;

    @GetMapping("/calendar/{date}")
    public String displayTasksByClick(@PathVariable("date") int date, Model model) {
    
        long userId = this.getCurrentUserId(); // just a method to get the user id requesting the task

        List<Task> taskList = taskService.findByDateAndUserId(date, userId); 
        model.addAttribute("taskList", taskList);
        return "/calendar";
    }

And calendar.html looks like this (I'm only pasting the relevant part)

<html lang='en' xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset='utf-8' />
        <title>Dashboard</title>
        <link rel="stylesheet" href="../static/css/calendar.css">
        <script src="jquery-3.5.1.min.js"></script>
  </head>
  <body>
      <ul style="list-style-type: none; margin: 0;">
        <li><a th:href="@{/calendar/20220228}">show</a></li>
        <li><a th:href="@{/calendar/20220301}">show</a></li>
        <li><a th:href="@{/calendar/20220301}">show</a></li>
      </ul>
  ......
       <div th:each="task : ${taskList}">
           <label th:text="${task.name}"></label>
       </div>

  <!-- the rest is irrelevant to the question --!>
  .......
 </html>

So whenever I click on the <a> elements, the client sends a request to the server, and the URL is handled by GetMapping method, returning the tasks. But while this happens, the page is also refreshed. Is there a way to display the tasks without having to refresh the page?

I tried returning void from the display method, but Spring ends up automatically returning /calendar/{date}, and it's still not what I want

@GetMapping("/calendar/{date}")
public void displayTasksByClick(@PathVariable("date") int date, Model model) {
    
    long userId = this.getCurrentUserId(); // just a method to get the user id requesting the task

    List<Task> taskList = taskService.findByDateAndUserId(date, userId);
    model.addAttribute("taskList", taskList);
}
